To all whom it mayconcem:

Be it known that I, WILLIAM MARION a resident of Sawtelle, in the county of Los Angeles and State' of California, have invented a new and Improved'Oil-Spreader, of,

which the following is a full, clear, and exact description. y v

This invention relates to oil spreaders, and is particularly useful in connection with devices of this character used for spreading oil, tar, asphaltum and the like uponroads.

The object of the invention is to provide an oil spreader which is simple, strong and durable. in construction and by means of which the fluid is forced into the roadway under-V neath the surface of the same.

The invention consistsin the construction and combination o f parts to be more fully described hereinafter and l particularlyset forth in the claims. Y

Reference is to be had to the accompanyication, in which Figure 1 vis a side-elevation of my invention as attached to a tank vehicle, showing parts in cross section; Fig. 2 is .a rear elevation of a part of the device; view of a detail showing partsin cross-section; and Fig. 4 is a side elevation of the plow member of the device.

My invention may be attached to a vehicle of the usual kind, adapted` to contain oil or other liquid in a tank that is supported for progressive movement on wheels; and is -provided with a plow whichis adapted to be forced along underneath the surface, of a roadway at a suitable depth, and has means f for discharging the oil underneath said plow to thoroughly impregnato the road material therewith, at a distance below the surface.

In Fig. 1 the device is shown mounted at the rear of an ordinary vehicle 1, provided With a tank 2 adapted to contain the oil. I provide a frame work end member 4 securely bolted to the longitudinal members 3 near the rear ends thereof. At the rear end of the framework is secured a transverse axle 5, the ends of which are downwardly disposed and are provided with wheels 6 adapted to roll upon the surface of the roadway and to' maintainthe frame at a .suitable hei ht thereabove. The framework is provi ed with a transverse member 7 spanning the the United States, and

verse bar rigidly secure the plow to the bars 8.

part of this speci- Fjig. 3 is atop space betwee the longitudinal members 3, to-which are secured downwardly projecting bars 8, of tria lar cross section, 'presenting anvedge towar the vehicle. At theends of the bars 8 is secured a plow member 9, comprising a horizontal lower plate 10 and an uchned upper plate 11, which form a knife e ge the lower plate'lO has an upwardly disposed edge or flange 13 to which 1s riveted a trans- 14.- The bars 8 'extend downwardly, passing through suitable' openings in the upper plate 11, and have forwardly disposed toes 15 which are located in the space between the plates 10 and 11. Rivets 1.6, passing through thel plates and the toes,

lars '17 are upwardly secured to the framework and are adapted to prevent the rearward displacement or 4bending of the bars and the plow as the device is moved forwar e r A cylinder 19 is mounted above the frame- V work transversely of the same, and has an upwardly extending elbow 20 which coin- Inunicates, by means of flexible piping 21,

with the outlet 22-of the Vtank 2. i A valve rality of pipes 25 extend downwardly from the cylinder 19 and are secured in openings communication between the cylinder 19 and thechamber' '24 formed between the upper and lower plates of the plow and the laterally disposed edge 1? of the lower plate.

upper plate, but is lso arranged that a narrow slot, extendin the width of the plow, is left between theA edge and the upper plate. Each of the pipes 25 is provided with a valve 26, by means of which the liow of the oil therethrough may be regulated.

der 19 and from the latter into the 24. To revent the oil from' flowing out through t e sides of the plow, side-plates 27 are provided, which are secured by angles28 and anged edges 29 to the upper and lower plates respectively. As the lplow is drawn I along with the movement of t e vehicle, it is i forced forward under the surfaceof the roadway and the material composing the same Colmounted upon the bars 8 and have extending braces 18 which are This edge 13 does not extend quite to the The oil from thetank flowsA into the cylin. -chamber 12 at their junction. The rear end of 23 is located at the outlet to regulate the iow of the oil into the cylinder 19. A pluin the upper' plate 11, thereby establishing IOO slides over the inclined upper late 11. The oil within the chamber 24 t us flows out therefrom and impregnates the material of the road as the plow moves forwardly. The bar 14 secured to the upwardly disposed edge of the lower plate, hasa beveledV edge which facilitates the smooth flow and even distribution of the oil from the chamber 24. It will be understood that by thus forcing the oil underneath the surface of the roadwa the latter is consolidated and rendered ust-proof far more easily than if the liquid were merely applied as a surface dressing in the usual manner. The amount of liquid which is supplied to the roadway can be nicely regulated y the valvesin the feed pipes to the plow. As the lower plate of the plow is horizontal, and as the wheels 6 maintain the frame at the same height above thesurface of the roadway, the plow itself will be maintained at the same level below the surface of the roadway as it is moved forward under the same.

The upper plate 1 1 extends rearwardly beyond the lower late 10 thus forming an open s ace into which the oil may flow freely from t e chamber 24, and thereby preventing the earth raised bythe u per late from falling -back into position be ore` t e lower` stratum has become impregnated with the liquid. Furthermore, this prevents the raised earth from clogging up the oil outlet and insures an even distribution of the li uid.

Having thus: describe my invention, I claim as new and desire to secure by Letters Patent:

1. In an oil spreader, a wheeled frame, an oil tank on the frame, a plow depending 'from the frame, said plow comprising upper and lower plates secured together at their front edges to form a cutting edge and arranged transversely of the frame substan-` tially the full width thereof, said upper plate being of eater width than the lower plate, and over anging the said lower plate at the rear thereof, said lower plate being provided at its rear edge with an upturned ange s aced apart from the lower face of the upper p ate, plates secured to the ends of the upper and lower plates and forming with the upturned fiange and the lower plate a receptacle, a transverse cylinder above the plow and connected with the oil tank, and a plurality 0 passages between the cylinder and the p ow.

2. 'In an' oil spreader, a frame, a plow deending from the frame, said plow comprismg up er and lower plates secured together at their front edges to form a cutting edge and arranged transversely of the frame substantiall the full width thereof, said upper plate being of greater width than the lower plate, and overhanging said lower plate at the rear thereof, said lower plate being provided at its rear edge with an upturned flange spaced apart from the lower face of the upper plate, plates secured to the ends of the upper and lower plates and forming with the upturned flange and the lowerplate a receptacle,land means for supplying oil to the receptac e.

3. In an oil spreader, a frame, a plow deending from the frame, said plow comprising upper and lower plates secured together at their front edges to form a cutting ed e and arranged transversely of the frame su stantially the full width thereof, said upper plate being of greater width than the lower plate and overhanging said lower plate at the rear thereof, said lower plate being formed into a receptacle for oil, and means for supplying oil to the receptacle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
